The Crystal Prison by Robin Jarvis ( The Deptford Mice Triolgy Book 2)

An innocent young mouse lies murdered in a moonlit field as the screech of an owl echoes across the ripening corn. The Deptford Mice have escaped the horrors of Jupiter’s lair and sought refuge in the countryside. But once again they must face terrifying evil as they are embroiled in a series of horrible murders. At first the simple country mice suspect Deptford newcomer Audrey – but the truth turns out to be far more sinister.

Robin Jarvis worked in television and advertising before becoming a full-time author and illustrator. His first book, The Dark Portal, was short-listed for the 1989 Smarties Book Prize in England. Mr. Jarvis currently lives in London.
